You are talking about a truck diesel then,"in-frame" implies liners et al.
American car engines generally don't have removable liners and almost always
need block machinework, unlike UK and Euro counterparts.

Do you cruise the boulevards of California at an average of 190 to 240 mph?
That's the only way you would be using anything remotely like 800 hp in a car
or light truck for more than several seconds at a time. Offshore racing boats
run big block Chevys wide open at 700-800 hp. An engine probably is good for
one race between 'freshenings' and in any event nothing but the block and heads
is even going to be considered for more than a few races. Often not even those.

TBO of a Top Fuel or Funny Car engine is five or six seconds. They change
pistons and rods between runs.

Put your monster big block up to a 500 kw three phase generator, geared to the
correct speed, and hook up a big gas tank. See how long it lasts at 800 hp, or
even 600.

You've never been in California on Friday nights, and watched them
lope though.

Are you saying the Cummins Signature 600 isn't modern? Of course this
is not that big either, it might start the starter engine for a
Wartsila or Sulzer...
